The Ferrari 150° Italia, formerly known as the Ferrari F150, is a Formula One motor racing car built by Scuderia Ferrari Marlboro to compete in the 2011 Formula One season. It was launched at Ferrari's headquarters in Maranello, Italy on 28 January 2011,[2] one year to the day after the launch of its predecessor, the Ferrari F10.

The car's chassis designation has been chosen to celebrate the 150th anniversary of Italy's unification,[3] although this has been seen by some pundits as a political move by Luca di Montezemolo following criticism for Ferrari's failure to secure the 2010 World Championship at the 2010 Abu Dhabi Grand Prix.[4] It was driven by 2005 and 2006 World Champion Fernando Alonso and 2008 championship runner up Felipe Massa.

In February 2011, Ford declared its intention to sue Ferrari over the use of the F150 name, to which Ford owns a trademark.[5] In response, Ferrari began to refer to the car as the "F150th Italia", claiming the original F150 moniker was simply an abbreviation.[6] On March 3, Ferrari announced that the name had again been tweaked to "Ferrari 150° Italia" (the 150º pronounced as the Italian ordinal centocinquantesimo), and that Ford had withdrawn its legal challenge.

[When the season began in Australia, many were surprised by Ferrari's noticeable lack of pace, particularly in qualifying. Alonso and Massa were 1.4 and 2.0 seconds slower than polesitter Sebastian Vettel in his Red Bull RB7, respectively. In the race however, the Ferraris certainly seemed to have decent pace, but their finishing results were still substantially hampered by their poor grid positions, with Alonso finishing 4th and Massa 7th. Their lack of pace continued to hinder their results in both Malaysia and China and after three races, they remain without a podium position and sit third in the Constructor's Championship, already 55 points down on leaders Red Bull. Turkey saw a change in pace for Ferrari, as they were finally able to keep pace with Red Bull. After starting from fifth, Alonso managed to make his way up to second, before being passed by Mark Webber on the 51st lap. His third place finish was Ferrari's first podium of the season.

Massa, meanwhile, started from tenth place, after mechanical problems prevented him from setting a time in the third qualifying session. Although he managed to get as high up as sixth place, two botched pit stops meant he could only finish 11th, behind Kamui Kobayashi and outside the points.In Spain, Alonso qualified 4th but at the start of the race managed to pass all three drivers ahead and take the lead. But Ferrari again showed a lack of pace and after two rounds of pit stops Alonso found himself behind Mark Webber, who at the time was third. When Alonso switched to hard tyres, the situation became even worse and he was soon overtaken by Jenson Button and was eventually even lapped by race winner Sebastian Vettel, thus finishing in fifth.In Monaco, Ferrari was unable to do better than 4th in qualifying. Alonso again had a good start, passing Webber for third.

After the Safety Car, Alonso, having pitted, found himself some 10 seconds behind leader Vettel, but having new tyres, started to catch Vettel quickly and soon found himself just behind him. Meanwhile, Button, having pitted after Alonso, had tyres in even better shape than the Spaniard, and he too started catching Alonso and Vettel and soon found himself behind Alonso. Alonso would probably have had a great chances to overtake Vettel but Vitaly Petrov and Jaime Alguersuari had an accident which led to the race being suspended. After the restart, the top three drivers managed to hold their places so Alonso finished 2nd.In Canada, the hard-braking, low-downforce track made the Ferraris show much better pace in qualifying than before with Alonso and Massa taking 2nd and 3rd, respectively, with Alonso just over tenth behind pole sitter Vettel.

However, race conditions were bad and after a bunch of pit stops and a delay of the race Alonso was hit by Button and thus had to retire from the race.The race in Valencia saw the ban on engine mapping which prevented some teams, especially Red Bull from running extreme engine mapping in qualifying, and thus prevented them being so dominant in qualifying. In the race however, it didn't change much of the Red Bull's race pace so Vettel got away early, while Alonso had to be satisfied with 2nd, which he got after overtaking Webber.
